Question about Car Audio & Video
Maybe. Some, but not all, 4-channel amps can be bridged. You'll need to provide a specific brand and model number for a more definitive response.
On many bridgeable amps, the connections are shown right on the output terminals, usually the "+" of one channel and the "-" on another channel. The connection diagram in your user manual may also show which channels are bridgeable and the appropriate connections. Some amps may support what they call "tri-mode", powering both full-range speakers and subs at the same time.
Using a multi-channel amp with the channels bridged to power subs is a compromise. While you'll get an increase in power, it usually isn't as much as you would get from a monoblock. And fine tuning for the best sound is more complicated, balancing the filters and crossover so that the correct frequencies are sent to the appropriate speaker.
Hope this helps.
